Description

  The present invention relates to a method of operating a textile machine, a spinning preparation machine, preferably a strip in which the fiber material is stored in a can at a supply rate determined in the region of the textile machine outlet by a storage device such as a coiler plate. Machines, carding machines, combers, textile machines, in particular outlets for textile materials, and coiler plates for storing textile materials in at least one can with a predetermined supply The invention relates to a spinning preparation machine in the form of a drawing machine, a carding machine, a comber, having a storage device arranged in the area of the outlet, etc.

Spinning preparation machines such as drawing machines, carding machines and combers are used, among other purposes, to make the incoming fiber material more even.
To achieve this objective, the spinning prep machines are mutually connected so that the fiber material is guided along a so-called nip line, transversely to the band between the rollers. It has a series of drafting systems in the form of a plurality of rollers arranged.
The fiber material is finally stretched and simultaneously made uniform between the rollers.
After the above process, the fiber material in the form of flakes is finally put into a container known as a can where the fiber material is made into a circular or oval loop by a storage device such as a coiler plate. Stored in.
Thereafter, the filled can is replaced by a corresponding empty can and transferred to a downstream textile machine such as a spinning machine.

However, because of the satisfactory quality of storage, frictional force transfer between the storage device and the fiber material is required, which is a troublesome problem due to the structure of the can itself, especially at the beginning of storage in an empty can. Occurs.
The cans used are equipped with one or more helical springs that press the bottom of the can from below and keep the can in an optimal position for storage.
Also known is a can having a rectangular cross section in which at least two helical springs are arranged adjacent to each other in the longitudinal direction of the can.
In order to stabilize the can bottom horizontally, a pantograph system or a folding grid system is used for such cans.
The upwardly acting spring force ensures that the can bottom of the empty can rises at least to the top edge of the can when storage is initiated to ensure that the aforementioned friction exists to guide the fiber material. It has become.
The can bottom is then continuously pulled down throughout the storage process by the weight of the product so that the guide is maintained.

As mentioned above, the spring system will wear out or become dirty as service duration increases while raising and lowering the bottom of the can completely works on the new can, so the remaining spring force will cause the empty can to It is not enough to push the bottom of the can up to the top filling position of the can.
For example, if the can is placed at the outlet of the traction system, the distance between the discharge unit in the form of the bottom of the coiler plate and the opposite can bottom will eventually become too large.
In this case, the fiber material is not stored regularly and can slip uncontrolled over the bottom of the can and, in the worst case, be thrown out onto the edge of the can.
Spring tolerances have similar results, and the main parameters of the spring, such as material, length, and spring constant, must be selected relatively accurately in order to apply the correct force to the can bottom.

  In the foregoing case, the fiber material stored at the beginning of the filling process will be at a low quality level due to insufficient frictional bonding between the fiber material and the storage device or can.

In order to address this problem, for example, DE 3621794 A1 proposes gradually lowering the can bottom from its upper position during the storage process by means of a vertically movable ram.
The lowering is performed so that the compressive force acting on the stored web packets generated from the contact of the most recently stored web cycloids is substantially constant during the entire storage process.
To achieve this goal, the compressive force acting on the web packet is captured and the deviation of this force from an adjustable value is determined.
Thereafter, the ram is actively moved by the driving means depending on the above deviation.

  Similarly, DE 19611500 A1 describes an active drive device for adjusting the height of the can bottom, where the bottom of the can bottom is a force and / or distance taking into account the filling level of the can Is controlled by measuring.

  However, such systems have the disadvantage that additional components exist and the drive device increases procurement and maintenance costs.

  Accordingly, the object of the present invention is to propose a textile machine and a method of operating this textile machine that allows for clean and controllable storage of the textile material in a conventional spring-supported can even at the start of the storage process It is to be.

The purpose is that as soon as the fiber material present in the can comes into contact with the storage device, an electrical signal is generated by the sensor during storage of the fiber material, and the supply of this storage device is fed back using this electrical signal. This is achieved by being controlled by a loop.
The fact that controlled storage is possible with a higher supply than a certain supply only if the storage device, such as in the area of the underside of the coiler plate, comes into contact with the fiber material already stored in the can This is addressed in a simple but reliable manner, because the fiber material is initially guided to correspond in all aspects at this point.
The point at which contact is made is thus an important parameter addressed by the method according to the invention in the control of the feed rate.
In this connection it is noted that the detection of this signal does not necessarily have to result in an immediate change in supply.
It is also conceivable that the signal strength is taken into account and that the corresponding adjustment is made only after reaching a certain signal strength or only after a certain time after the signal is detected.
In this way, it is ensured that the feed rate cannot be increased too quickly and a reliable storage of the fiber material is ensured.

In this connection, it is particularly advantageous if the supply is increased as soon as the stored fiber material and the storage device come into contact.
As mentioned above, the fiber material is not all slipped at this point so that the flakes do not slip out of control inside the can or in the worst case can be thrown out of the can during storage. Guided on the surface.
The storage device is operated with a first supply at the start of storage of the fiber material in the empty can and with at least one second supply after detection of contact, wherein the first supply is Is lower than at least one second supply.
In particular, problems with web storage can occur when the can spring system is unable to push the can bottom to the highest filling position at the start of the storage process, such as after a can change, or when the textile machine is started. Occur.
If the storage device supply is selected to be too high during this stage, storage errors can occur, in which case the fiber material is stored unevenly or canned May be drawn over the edges.
As a result, the machine stops and / or the quality of the fiber material is reduced.
It is already known that the supply at the start of storage is kept at a lower level for a certain time.
However, this time is often insufficient for poorly stored cans or too long for new cans, so the textile machine is operated more slowly than needed. .
In the method according to the invention, the supply of the storage device is kept at a first lower level until contact between the stored fiber material and the storage device is detected.
Achieving this contact serves as a trigger signal to increase the feed rate to a second value that ultimately allows the maximum possible production rate for the textile machine.
Operation at just two different feed rates is possible, but it can also be raised to a final level in individual steps where the feed rate is subdivided as desired.
For example, to increase the supply gradually or incrementally until the signal from the sensor contacts between the storage device and the fiber material, the flakes may first be stored at a first low supply. It is done.
After this point, the necessary guide for the flakes has been established, so it is possible to increase to the maximum supply.

Since the smooth change of the supply rate ensures a gentle storage of the fiber material, it is also advantageous if the supply change is smooth.
However, it is also advantageous if the feed rate change is made in stages, the type of controller being dependent on the existing drive means of the storage device.

It is also advantageous if the signal is generated by a force and / or pressure sensor, contact sensor, proximity sensor, optical sensor and / or sensor for detecting friction between the textile material and the storage device. .
Such sensors are available in a wide variety of versions and are selected to suit the type of textile machine.
Of course, other sensors, such as probes that respond to bending, are also conceivable if the sensor conforms to the configuration of the storage device.
Different sensors can be used together to increase the reliability of detection.
With respect to these sensors, it should be further clarified that when the fiber material comes into contact with the storage device, the sensor sends a signal to the controller to control the feed rate, since this is because the flakes This is because it indicates that it is guided by or about to be guided by the storage device.
After this point, it is advantageous to control the feed rate as in the present invention.
In this connection, it is also conceivable that the control is involved only after a certain time delay after the first contact.
It should be further clarified that a sensor is implemented to generate a signal as soon as it comes into contact with the fiber material stored in the can.
Non-contact control of the fiber material is also possible.
For example, a light sensor, preferably a transmitting and / or receiving unit corresponding to the light curtain, can also be arranged directly above the can or just below the outlet of the storage device.
This indicates that as soon as the sensor generates a continuous signal, the fiber material stored in the can has come into contact with the storage device.

It is further advantageous if the contact force exerted on the storage device by the stored fiber material is taken into account in the supply control.
As mentioned above, there must be a certain frictional connection between the fiber material and the can bottom or storage device for the high quality of the stored fiber material.
However, this frictional connection is proportional to the contact force exerted on the at least one component of the storage device by the stored fiber material, where the contact force is a spring that presses the can bottom in the direction of the storage device. Drawn from power.
After that, when this contact force is measured, parameters that take into account the individual state of the can are available, so the wear or sign of the can spring system or the sign of contamination does not actually disappear, Considered effectively when the can is filled.
For this purpose, reflecting the frictional connection between the fiber material and the storage device, such as the coiler plate of the drawing machine, in order to be able to finally operate the storage device with an optimal supply Only certain contact forces must be associated with a specific supply of storage devices that ensure clean storage.

It is further advantageous if the contact force is determined continuously or at defined time intervals.
Continuous measurement allows for precise adaptation of the feed rate, but in some cases, the contact force may be captured only at the beginning or end of storage to control these critical steps. .
It is further advantageous if a sensor is implemented that detects the contact between the fiber material and the storage device in order to capture the contact force so that the measurement of this parameter does not require an additional sensor.
For example, in this case, a pressure sensor is used.
Here the sensor provides a signal as soon as the flakes contact the storage device, but in this case the intensity or type of this signal also varies in proportion to the contact force of the fiber material, so that the contact force Can be guessed.

The contact force is averaged over a certain period of time, so that the average value obtained is used as a reference for controlling the feed rate.
Since the fiber material is stored in a loop, the fiber material has a non-planar surface in the can, so that the contact force at the sensor is also affected by variations.
However, if the contact force is averaged over a period of time, a number of measurements to be averaged are obtained so that the indicator measurement variable is available.

In an advantageous refinement of the invention, the captured contact force is processed by the controller and used to calculate the corresponding progress on the feed rate. In contrast to the direct adaptation of the supply rate to the detected contact force, this has the advantage that the control of the supply rate is performed as smoothly as possible.
Thus, for example, the supply rate at a certain time is calculated in advance depending on the increase in contact force.
This prevents the feed rate from being continuously adjusted only as a response to previously captured contact forces.
Also, since the pre-calculated value is corrected using the instantaneous captured contact force, the feed rate is always adapted as accurately as possible.

It is also advantageous if the supply rate is reduced again when a predetermined contact force is reached.
This is a sign of reaching the end of storage, as the contact force increases significantly as the maximum fill level of the can approaches.
Similarly, at this stage, it is advantageous to reduce the feed rate to end the storage process cleanly.
A gradual increase in contact force or a certain maximum value of contact force is selected as the trigger event.

  It is also very advantageous if the storage of the fiber material is completely stopped when a defined contact force is reached, where the corresponding contact force is absolute so that the actual spring force in each can is taken into account. The value is determined in advance or as the difference from the initial value when the can is filled.

Can type and / or dimensions, fiber material type, length of fiber material stored in the can and / or mass, production rate of textile machine, and / or temperature or humidity, etc. It is further advantageous if further parameters such as environmental conditions are taken into account in the feed rate control.
In this way, the method is best adapted because contact force alone is not sufficient to store the fiber material correctly.
The above data is input to the controller only once or continuously or determined by a corresponding sensor.

Ultimately, the textile machine according to the invention comprises at least one sensor implemented to generate an electrical signal as soon as contact is made between the textile material stored in the can and the storage device. , Characterized by being associated with a sensor connected to a controller implemented to control the supply of the storage device by means of a feedback loop using this signal.
This results in a textile machine that allows efficient and reliable storage of the textile material.
In this way, it is possible to use this signal to maintain the supply at the beginning of the storage process at a level that prevents the fiber material from being thrown out or stored in an uncontrolled manner. The feed rate can be adapted after contact between the fiber material and the storage device is detected, resulting in faster and more reliable storage of the fiber material.

In this connection, it is particularly advantageous if a controller is implemented to increase the supply rate as soon as the stored fiber material comes into contact with the storage device.
As mentioned above, at this point the fiber material is further guided by the storage device.
Thus, an increase in supply does not result in uncontrolled storage as in the beginning of the storage process.
Rather, further guidance allows for a significant increase in the production rate of the textile machine, since faster storage is possible at the point of contact.
Thereby, for example, the storage device has a first supply at the start of storage of the fiber material in the empty can and at least one second after detection of contact between the stored fiber material and the storage device. The first supply amount is lower than the at least one second supply amount.
This addresses the fact that reliable storage requires a specific contact force of the can bottom against the fiber material in a reliable manner.
However, for old and / or poorly stored cans, the can bottom of an empty can cannot be pushed to the highest filling level by the residual spring force of the spring system that pushes up the can bottom.
If the storage device is operated at a feed rate that is too high at this stage, there is a risk that the fiber material slips sideways off the can bottom or over the edge of the can.
In either case, clean storage would be nearly impossible.
However, if the feed rate is raised gradually only for the first time and only after the storage device and the stored fiber material come into contact, the above disadvantages are prevented and the textile machine is always at the maximum possible production rate. Be operated.

It is particularly advantageous if a sensor is implemented to capture the contact force applied to the storage device by the stored fiber material.
In this way, the supply amount can always be adapted to the actual filling height of the can, taking into account the contact force, but in this case the opposite force acting on the can bottom directly by the spring system associated with the can bottom is directly There is no need to be known.
Rather, the counter-force described above is indirectly accounted for by the contact force, but in this case the supply of the storage device is always maintained at the maximum value that allows just clean storage.

It is also advantageous if a controller is implemented for reducing the supply rate or stopping the storage of the fiber material as soon as the stored fiber material exerts a defined contact force on the storage device.
As a result, it is always ensured that the feed rate is high enough to allow clean storage of the fiber material.

  It is also advantageous if the sensor is a force and / or pressure sensor, a contact sensor, a proximity sensor, a light sensor and / or a sensor for detecting friction between the textile material and the storage device, where Reference is made to the above embodiments with respect to these advantages.

When at least one sensor is arranged in or on the bottom surface of one component of the storage device so that one component of the storage device can contact the top layer of the fiber material stored in the can Is particularly advantageous.
This allows a reliable direct measurement of the contact force, but of course other arrangement positions are also conceivable here.
It is also possible to determine the contact force indirectly, for example, by measuring the power consumption of the storage device that increases as the contact force increases.

The contact force can be detected over a period of time and converted to an average value using a controller, and the resulting average value can be used to control the supply rate. It is further advantageous when used as a reference for
This compensates for sensor measurement variations, so that a particularly reliable value is provided to control the supply. Since statistical data is also taken into account, the measured values are supplied to control the supply over an arbitrarily long period of time.

In a further advantageous embodiment of the invention, the textile machine is a sensor in contact with the controller, by which the type of can and / or dimensions, type of textile material, stored in the can Additional parameters such as the length and / or mass of the fiber material, the production rate of the textile machine, and / or environmental conditions such as temperature or humidity are detected and used to control the feed rate. With additional sensors.
Control solely based on contact force is certainly an important improvement over the prior art.
However, if additional factors are taken into account, this control is further refined and adapted to the current conditions.

  In order to make the adaptation of the storage speed as accurate as possible, it is further advantageous if the storage device is equipped with drive means whose drive speed is changed continuously or incrementally.

It is also advantageous if at least one sensor is activated or deactivated.
For example, it may be advantageous to deactivate the sensor after the initial filling phase and reactivate the sensor only after changing the can.
It is also redundant to control the feed rate at the start of storage to process certain fiber materials so that the textile machine can operate during this period without measuring contact force .

Further advantages of the present invention will be described with reference to the following drawings.
Side view of the drawing machine. Sectional drawing of the coiler plate of the drawing machine by this invention. The figure showing progress of the electric potential of contact force and supply amount as a function of time. The side view of the storage device of a drawing machine at the time of the start of fiber material storage in a can. FIG. 5 shows a side view of the storage device according to FIG. 4 after a certain storage time. FIG. 3 is a plan view of a partially filled can.

FIG. 1 shows a side view of a drawing machine as an example of a textile machine according to the preamble of the independent claim.
During operation of the drawing machine, the flakes 2 are taken out from a plurality of so-called drums 1 and supplied to the drawing system 3 of the drawing machine.
The traction system 3 is composed of three or more pairs of rollers 4, each roller pair 4 comprising a lower roller and an upper roller, resulting in homogenization of the flakes 2 by different rotational speeds by traction (draft).

Downstream of the traction system 3, the pulled fiber material 5 is finally supplied to a rotating coiler plate 7 by a calendar roller pair 6 and stored in a loop in the can 8 by the coiler plate 7.
In order to prevent the fiber material 5 from slipping in the can 8 uncontrolled, the can has a spring system 9 that presses the can bottom 10 towards the coiler plate.
This creates a friction connection between the fiber material 5 and the can bottom 10 and the adjacent surface of the coiler plate 7.
The friction connection described above guides the fiber material 5 to ensure that the fiber material 5 is stored in a uniform loop in the can 8.
During the filling process, the can bottom 10 is constantly moved downward by the weight of the fiber material 5, so that the contact force acting on the fiber material 5 and the coiler plate 7 remains constant in the ideal case.

However, if the spring system 9 is deteriorated due to fatigue or contamination, the can bottom 10 cannot reach the highest filling level of the can bottom 10 as shown in FIG. 1 even if the can 8 is empty.
If the fiber material 5 is discharged into the can 8 with a supply that is too high, the fiber material 5 may be stored unevenly and in the worst case it may be thrown out, so the machine stoppage Inevitable.

Therefore, according to the present invention, the storage device supply is a signal indicating the contact between the storage device produced by the sensor 11 and the fiber material 5, and in the advantageous refinement of the present invention, the stored fiber It is proposed that the material 5 be controlled by a feedback loop using a signal that is proportional to the bottom surface of the coiler plate 7, that is to say a contact force acting on the storage device. The supply amount of the storage device is preferably first reduced by the method according to the invention until a certain contact force is achieved by the initially stored fiber material 5 resulting in a determined signal strength. Maintained at level.
Achieving this predetermined contact force serves as a starting signal to increase the feed rate to a second value that ultimately allows the maximum possible production rate of the textile machine.
Of course, it is also possible to increase the feed rate in any number of individual steps from the first level to the desired final speed, this increase taking place starting from the time of detection of this signal.

The contact force is measured by the sensor 11, for example, by a force measurement sensor integrated with the bottom surface of the coiler plate 7 as shown in FIG. 2.
Using this sensor 11, it is possible to capture the contact force continuously by the controller or at fixed time intervals, and these measurements are prior to controlling the feed rate. Associated with other parameters such as the type or size of the can 8.
Although FIG. 2 shows only one sensor 11, the coiler plate 7 may be provided with a plurality of the same or different sensors.

FIG. 3 shows a possible progression for the contact force (curve A) and the supply rate v (curve B) as a function of time t.
As shown by these curves, the supply amount of the coiler plate 7 at the start of filling of the can (t ₁ ) is the fiber material 5 even if the can bottom 10 has not yet reached the intended filling height. Is raised to a constant value v ₁ until time t ₂ when it is guaranteed to be stored cleanly in the can 8.
By storing the fiber material 5, the time point t ₃ is finally reached, where the fiber material 5 contacts the coiler plate 7 to generate a contact force, resulting in a signal detected by the sensor 11.
Signal strength by the contact force described above, between the contact force and the spring force of the spring system 9 from this point, but increases continuously until time t ₅ for certain equilibrium is reached, where the spring force, Accordingly, the contact force is also slightly increased by the compression of the spring system 9.

When a predetermined contact force F ₁ (time t ₄ ) is reached that guarantees a reliable and controlled storage of the fiber material 5, the supply amount of the storage device, ie the production speed of the drawing machine is finally reached Is increased by the controller until a level v ₂ corresponding to the maximum possible production rate is reached (time t ₆ ).

Alternatively, after the sensor 11 has sent a signal indicating the contact between the fiber material 5 and the storage device, i.e. a signal indicating the presence of the required guidance of the fiber material 5 by the storage device to the controller of the textile machine, the supply also conceivable that the amount is already increased at time t _3.

  Although FIG. 2 shows a linear control of the storage device supply, this can take on any other progression to achieve optimal control.

  FIGS. 4 to 6 show the storage progress of the fiber material and the possible contact between the fiber material 5 already stored in the can 8 and the storage device shown in FIG. And shows a further possibility for monitoring (the detailed form of the coiler plate 7 with the corresponding penetration force for penetrating the fiber material 5 supplied from above is omitted).

As these figures show when viewed together, the sensor 11 is implemented as a light curtain comprising a light source 12 and a corresponding reflector 13 as shown.
Such a light curtain can detect whether the fiber material 5 is present in the beam path (dashed line).
In the example shown, the light reflected by the reflector 13 is detected by a detector (not shown) located on one side of the storage device with the light source 12 (of course, the detector and the light source 12 are connected to the storage device). If placed on a different side, the reflector 13 can also be replaced by a detector).

Thus, the method of operation of the present invention is as follows: the circular motion of the coiler plate 7 and the inherent rotation of the coiler plate 7 (see FIG. 6). The fiber material 5 is stored spirally by these corresponding motions. ), The fiber material 5 is always stored at different points with respect to the can bottom 10, so that as soon as the fiber material 5 is stored on the can bottom 10 from above, the light beam emitted by the light source 12 is regular. Interrupted at time intervals.
Therefore, as a result of this, the resulting pulsed signal of the light curtain shows that the fiber material 5 is already stored in the can 8 but the fiber material 5 and the coiler plate 7 are not yet in contact. Show.

As soon as this is the end (see FIG. 5), the light curtain is permanently interrupted, so that the contact between the fiber material 5 and the storage device associated with controlling the feed rate of the coiler plate 7 is It is detected with high reliability.
Thereby, it is also possible to transfer the signal to the controller only if the light curtain is interrupted for a certain period of time.
In this way, the pulsed signal detected at the start of storage is already filtered out prior to transfer to the controller.

Alternatively, rotating the coiler plate 7 only about the axis of rotation to which it is fixed, and performing the storage of the fiber material 5 by superimposing the rotation of the coiler plate 7 and the corresponding rotation of the can 8. to enable.
In this case, the axis of rotation of the can 8 is parallel to the axis of rotation of the coiler plate 7 and results in the stored flake loop shape shown in FIG.

The advantage of such an embodiment lies in the fact that the coiler plate 7 is arranged outside the beam path of the light source 12, as shown in FIG.
In this case, the light beam is interrupted only when sufficient fiber material 5 has been stored in the can 8 so that the fiber material 5 and the coiler plate 7 are in contact, or at least just about to contact.

Further, the present invention is not limited to the illustrated embodiment.
As indicated in the drawings or as described in the claims or the description, any and all combinations of the individual features described appear to be capable of corresponding combinations and make sense. To the subject matter of the present invention.
